LabEx: The Best Alternative to Play with Docker

With the recent announcement that the Play with Docker and Play with Kubernetes systems will be unavailable starting March 1, 2026, many developers and educators are left searching for a suitable alternative. Play with Docker was a beloved platform for interactive, browser-based learning environments focused entirely on Docker and container technologies. Fortunately, LabEx has emerged as the ideal alternative, providing a powerful and stable Docker Playground that delivers an excellent hands-on learning experience.

​
The End of Play with Docker

A deprecation notice has been officially issued for the popular playground: “The Play with Docker/Kubernetes systems will be unavailable starting March 1, 2026. Please visit Docker Docs for supported labs and guides.” (Play with Docker GitHub). While documentation is helpful, for those who relied on the instant, browser-based interactive environment of Play with Docker, finding a direct, hands-on replacement is crucial.

​
